Type alias KeyspaceReplicationOptions

Represents the replication options for a keyspace.

Two replication strategies are available:

• SimpleStrategy: Use only for a single datacenter and one rack. If you ever intend more than one datacenter, use the NetworkTopologyStrategy.

• NetworkTopologyStrategy: Highly recommended for most deployments because it is much easier to expand to multiple datacenters when required by future expansion.

If no replication options are provided, it will default to 'SimpleStrategy' with a replication factor of 1.

Example

await dbAdmin.createKeyspace('my_keyspace');

await dbAdmin.createKeyspace('my_keyspace', {
  replication: {
    class: 'SimpleStrategy',
    replicatonFactor: 3,
  },
});

await dbAdmin.createKeyspace('my_keyspace', {
  replication: {
    class: 'NetworkTopologyStrategy',
    datacenter1: 3,
    datacenter1: 2,
  },
});
